The first official trailer for writer/director Gavin Hood’s VFX-heavy, intergalactic adventure “Ender’s Game” is here.

Oscar winner Hood (“Tsotsi,” “X-Men Origins: Wolverine”) has written and directed the dystopian sci-fi adventure from the 1985 novel by Orson Scott Card. Asa Butterfield (“Hugo”) plays Ender, a preternaturally gifted child taken to the Battle School to prepare for the next alien invasion that looms in the near future. The film also stars Harrison Ford, Viola Davis, Ben Kingsley, Abigail Breslin and Hailee Steinfeld.

Like the teaser poster, Summit is aiming this at core fans of the book, which I am finally catching up with; it’s a smart, tough look at adults exploiting kids and forcing them to survive their own power games as they develop the skills to save the planet.
